Specification of Letters Patent.

Patented Sept. 14, 1915.

Application filed August 12, 1912. Serial No. 714,581.

To all whom it may concern:

Be it known that I, FRA1\*K HAMACHEK a citizen of the United States, and resident of Kewaunee, in the county of Kewaunee and State of 1V isconsin, have invented new and useful Improvements in PomSeparators, ofwhich the following is a description, reference being had to the accompanying drawings, which are a part of this specification. I

This invention relates to pea separators which operate upon the crop of pea vines as harvested and by keeping the vines well separated and subjecting them to blows of rotating boaters causes the pods to break and liberate the green peas which are then sifted from the pods and vines and imme diately discharged to avoid injury to them.

The objectsof the present invention are to improve upon details of construction of pea separators generally and particularly of the pea separator construction illustrated and described in my application for pea hullers and separators which resulted in Letters Patent No. 1,035,184, dated August 13, 1912.

One of the objects of the invention is to provide stationarydischarging fingers at the discharge end of .the sifter drum which extend downwardly and obliquely from the discharge opening of the drum in order to engage vines which may partially extend through the opening and thus cooperate with the turning of the drum in drawing vines out of the drum and preventing their accumulating at the discharge opening.

Another object of the invention is to provide a slotted, grooved chute leading from the discharge opening'of the sifter drum with agitator wheels turning through the slots thereof to engage the tailings and lift them and shake them while they are somewhat restrained in their travel by means of adjustable spring teeth above the chute and throughthis shaking and combing out operation oifect the separation of such peas as may have gone through the sifter drum with the tailings, the grooves of the chute affording a clear passageway for the discharge of such peas.

Another object of the invention is'to improve upon details of construction of the tailings conveyor by means of which the tail-' ings are discharged from the separator, whereby peas from the discharge chute and from the tailiiigs may freely roll down the tailings conveyor while the tailings are boin lifted thereby.

Another object of the invention is to improve upon various details of construction of pea separators. v

lVith the above and other objects in view the invention consists in the pea separator as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views: Figure l is a central longitudinal sectional view of a pea separator constructed in ac cordance with this invention; Fig. 2 is an end view thereof at the discharge end of the machine, parts being broken away. for clearness of illustration; Fig. 3 is. a transverse sectional view of the sifter drum and its boaters: Fig. 4 is a detail sectional view of one end of the sifter drum; Fig. 5 is a detail. sectional View showing the construction of parts at the discharge end of the sifter drum; Fig. 6 is a similar view at right angles to the view shown in Fig. 5; Fig. 7 is a transverse sectional view of the discharge chute for tailings; Fig. 8 is a sectional view showing the construction of the projecting teeth of thetailings conveyor belt; Fig. 9 is a plan view thereof; Fig. 10 is a view showing a modified form of tooth construction for the tailings conveyor belt; Fig. 11 is a plan view thereof; and, Figs. 12 to 19 respectively are end and plan views of the four forms of hulling boaters employed, and Figs. 20 and 21 respectively are edge and plan views of a hulling boaters.

In these drawings 10 indicates a frame of any desirable construction which has a shaft 11 journaled through it in bearings 12. This shaft carries a pulley 13 by means of which it may be driven from any suitable source of power. Between the bearings 12 the shaft has mounted on it a hexagonal or other desirably shaped body portion 14 provided with hulling boaters 17 which may be variously shaped and are preferably oblique modified form of with relation to the axis of the body portion so that the turning movements of the shaft 11 cause them to act as propellers or fan blowers for causing a current of air to flow in the direction of the rear or discharge end of, the machine catod.

Surrounding the body 14 with its hulling boaters is a sieve drum which has annular where the pulley 13 is losection.

state aoout .ly movement is given to the means oi chains 22 which engage 7 "Is or sprocket teeth 23 on the and which chains also t vheels 2 ion a counis journaled at the upper and is drivenv from the by :r oi. a sprocket wheel 26 2 connected by a chain 27 with el 28 on said shaft 11. The

drum is sub- 1 being construction thus Jar dethe present construction, how tudinal rods 29 corresponding to lifting rods 29 of my patented conever, ion" the vine strnction instead at lc-ein s were in cross section are preferably as shown in Fig. 3 d havetheir ed es beveled to fit with the tan ular sieve rames 30 containing persheet rubber or the like ans or-sievcs through the openings of which the hulled peas may freely The longitudinal rods 29 form bat-ten strips or :l'illets to cover the edges of no 1 rubber covering of the drum a therewith the inner wall of th in this construction also the lonl i rods have the row of closely spaced. ;ubular sievefin'gers 34 mounted-on them, but the ends of such fingers of each row are connected by bars 35 which extend from one end of the sieve drum to the other said bars 35 together with the. fingers 3d constitute lifting .ribs for lifting the vines, the bars 35 being longitudinal lifting members and the fingers 34 being spacing members for spacing said'lifting' members from the screening surface of the drum to atlord a space for the peas to pass between the screening surface and the lifting memhere. The fingers 34 and the longitudinal bars 35 may be formed together or may be made separate and connected together in any desirable manner, and the lifting rib may be mounted in the drum by having the fingers attached to the longitudinal rods 29 as by means of bolts. as shown in Fig. 4. These bars 3-5 may be of any shape in cross arious shapes being shown in Fig. as examples and serve to lift the vines and drop them upon the hulling boaters and at the same time inclose the space between the fingers or spacing members 3% to prevent the vines becoming caught therein.

The oblique plates 38 forming rake teeth positioned at the feed end of the drum and the oblique ribs or vanes positioned at the discharge end of the drum and other incidental structural features are the same as before except where specially noted. This is also true of the inclined separator apron beneath the drum directing the falling}; peas to the conveyor and the chat!" and dirt to the waste conveyor 58.

The hulling boaters LT preferably have the various forms illustrated. in Figs. 12 to 19 inclusive, the form shown in Figs. 12 and 13 being the hullingboaters at the feed end or" the drum with the long spike a at-thc forward end to catch the vines as they leave the feeder 83 while the inclined blade portion 5 deflects the vines inwardly to start their feeding movement through the drum. The

next series of hullin heaters oxtendin for some distance through the drum are those illustrated in Figs. 1 and 15 in which the spur c at the rear edge serves as a rake tooth in straightening the vines while the rounded beaded edge 03 as well as the curved face of the beater strike the pods with blows of sutficient force to open them and liberate the peas but by reason of their rounded surface avoid injury to the peas. For the remainder of the length of the sieve drum except for the last series the hdliing heaters .o of the type illustrated in Figs. 16 and l *srhich difier from the preceding type in that the spurs c are provided at both edges thereof as shown, thus increasing the combing action as the vines progress through the sieve drum and after they have had the greater number of peas freed therefrom. This combing action. serves to untangle thc vincs and expose the pods which were protected by surrounding vines from the blows of the heaters. The final set of hulling heaters is of the type shown in Figs. 18 and 19 and differs from the type shown in Figs. 16 and 17 principally by having; a greater obliqirity and this is for the purpose of more quickly discharging the vines from the drum when they have reached this point and preventing theiraccumulating in a mass to obstruct the 19 'asfbefore and on the end plate 44: at the bottom of the discharge end of the sieve drum are secured a seriesof downwardly extending oblique teeth 85 which are so arranged as to readily engage a projecting portion of a bunch of vines while being; carried around with the drum and as these teeth are stationary they tend to hold the vines while the drum turns away from them, thus assisting in the discharge of the vines from the drum. The teeth 85 being inclined are readily freed from the vines as the vines drop from the drum onto an. inclined corrugated chute 86 below the teeth 85. The downward movement of the vines on theinclined chute 86 is restrained somewhat by the presence of a stationary inclined rake 87 which is adjustably mounted on the frame at 88 to be capable of having its position changed to suit the requirements. The tines of rake 87 project toward the corrugated inclined chute 86 and serve to hold the vines if theyare in large masses and subject them to the action of rotating combing/ wheels 89. therebeneath. The combing wheels 89 are mounted on a shaft 90 which is journaled across the discharge hopper 69 beneath the chute 86 and have backwardly turned arms or fingers extending therefrom reaching through slots in the upper or crest portions of the corrugated surface of the inc ined chute 86 as shown in Fig. 6. The action of these combing wheels 89 is to thoroughly comb out and separate the bunches of vines which are sufliciently large to be engaged by the rake 87 and thus liberate the peas which may be entangled therein. Because of the corrugated surface of the inclined chute 86 the peas that are liberated readily separate from the tangled vines and pass down the trough portions of the corrugated surface. The inclined chute 86 discharges onto an inclined conveyor belt 91 which is in the form of an apron of canvas or other suitable material having slats 92 extending across it on its bottom surface to keep it in shape without forming shoulders for engaging and holding the peas which are discharged thereon by the inclined chute 86. In order that the vines may not slide down the conveyer 91, however, the slats 92 have fingers 98 projecting upwardly from them through the apron and these fingers may be formed integral with metal slats as shown in Figs. 8 and 9 or they may be of sheet metal construction secured to wooden slats as shown in Figs. 10 and 11, or they may be of any other desirable construction. The fingers arev preferably narrow so as not to present a surface at their meeting edge with the apron which would serve to hold loose peas and carry them up with the conveyer, thus leaving the peas free to roll down the conveyer while-the vines and other, tailings are carried upwardly by the conveyor and discharged from the machine. The pulleys 94 at the upper and lower ends of the conveyer 91 are provided with grooves 95 to.

receive the slats 92 and thus permit of the apron being kept tight at all times while also serving as a driving connection between the pulleys and the apron. 4

The operation of the pea separator of the present invention is substantially the same as that of the structurecovered by my co-pending application referred to, though the provision of the spurs on the hulling beaters in cooperation with the sifter bars serves to prevent the tangling and bunching of the vines by their combing action thereon. The sifter bars with their continuous unbroken inner edge serve to lift the material as with the fingered lifting ribs, permitting the peas to pass-between the fingers thereof while the vines are carried up and dropped upon the rotating beaters. The fingers 34 which constitute the spacing members for spacing the longitudinal lifting bar 35 from the walls of the drum to permit the loose peas to passfreely thereby while the vines are held by said bar may be placed close together, as shown, or as far apart as desired and they may be of any length suitable for the purpose. By thus permitting the loose peas to pass through the lifting ribs or between the lifting ribs and the walls of the drum they are afforded an opportunity to more quickly pass out of the drum, since they are not held in the trough-like formations between the lifting ribs and the walls of the drum, but are allowed to roll over the perforated screening surface of the drum until they find openings therein through which they fall. an unnecessary exposure to the action of the hulling beaters and are in better condition than when retained within the drum fora longer time. The lifting rib in the present invention consists of a series of fingers mounted on a longitudinal bar as before. but in this case the longitudinal bar, instead of being placed against the wall of the drum as before, constitutes the inner edge of the lifting rib so that the ends of the fingers engage the walls of the drum to constitute 'spaces through which the peas pass to es cape the lifting rib. The peas liberated by the impact of the hulling beaters against the pods quickly find their way through the openings of the perforated plates 33 and roll down the inclined apron 47 to the conveyor 50. Such peas as may be contained in the tailings, however, are more effectively recovered'as the vines are more quickly ejected from the sieve drum by their engagement with the stationary teeth 85 and thus the tendency of. the' vines to bunch at the discharge end of the drum is prevented and the action of the comb wheels 89 in cooperation with the retarding rake 87 serves to entirely separate vines which may be tangled so that the peas held therein may be liberated and may pass down the grooves of the inclined chute86 onto the apron of the con veyer 91; the construction of the conveyer being such that this separation of the peas fromthe tailings is possible. While the vines are effectively carried upward by the conveyer 91 such conveyer presents no ob- The peas are thus saved.

'struction to the dowmvard travel of the at their upper ends to the underside of the chute and passing through openings in the chute and extending downwardly and tor .wardly at some distance above the chute.

As stated the guard holds vines away from the surface of the chute and the action of the Combine; wheels 89 is not interferred with thereby, but the combing of the vines and the separations-f the peas therefrom is performed in the same manner as when the guards are not present.

in Figs. 20 and 21 there is shown the edge View and a plan view of a modified form of hulling heater in which the widthv oi the heater is the same as before, but the outer end of the heater is provided with a rearwardly extending arm c in alineinent with the oblique edge of the heater proper. The oloject of the projecting arm is to afford a greater heating surface without increasing the surface of the wet portion of the heater and thus gain a greater opening effect upon the pods without increasing the fanning effect which might cause the vines to beheld. by air pressure against the sieve plates.
